The last bow mounted quiver I used (or at least left on the bow) was in 1997. 10 yrs straight of hanging one in the tree.
It's convenient for quick follow ups no doubt about it, but it's also the weak link if you are looking for proper balance, quietness with many models, and to a degree stealth because you are waving around those bright fletchings.
I don't know how you bow quiver guys do it, I could just never get used to it.

So to answer the question I practice with it off.
